I've owned cats several times with mixed results. Just as with people, some are good and some are bad. My daughter asked us to take her orphan kitty because she couldn't keep it and we did. A year later, the sweet little kitty has ruined all the carpets in our house, driven us crazy by running in the door and hiding, caused a furor with our neighbors, scratched me up when trying to take it to the vet to get it fixed, then came home pregnant and the kittens crapped up the garage.
Now I'm a patient man, and I'll admit that not all cats are bad. But I'm perfectly willing to find out how many balloons this one will take. It will be poetic justice.
Feral cats will do that. As dangerous as it might be, you MUST get them fixed if you expect even a modicum of decorum.
